When using the minion method yes it will smoke heavily for the first 15 minutes or so till the pile gets hot enough to have burned off all the charcoal dust and what not, then it will settle down to a much thinner blue smoke. That is just the charcoal by itself.
Now for wood: as others said don't soak it. Just toss it in dry, and also as stated bury a few pieces down in the pile at the start. Wood also smokes heavily when first tossed into a fire till it gets heated to a certain point, then it also settles down to a thin blue smoke - unless it's green wood then it's going to smoke like crazy a lot longer.
On a
WSM you can pretty much just leave the top vent 100% open at all times, don't think I have ever reduced mine at all in the 5+ years I've had it - the vent is probably glued in place by now... lol. When light your
WSM all three bottom vents are 100% open, once temps get to about 200 close one vent, when temps hit 240 close second vent and adjust 3rd vent to approx. 50% closed. Your temps should stable out around 250, adjust 3rd vent as needed. If you want to run hotter leave 3rd vent 100% open and make adjustments with 2nd vent as well.
If for some reason you ever have to add charcoal to a smoker get it at least half lit in a
chimney starter BEFORE tossing it into the pile. If you dump cold charcoal on a lit pile you will get that heavy start up smoke again.... only now your meat is in there! Also when you pull the lid off you may get a bit of heavier smoke due to the fire getting a big gulp of oxygen, but it will settle right down once the lid is back on.
Here are some recent runs on my
WSM with a bit of Ninja smoke going on.
